Available on crate feature dep_sdl3 only.

Render a list of triangles, optionally using a texture and indices into the vertex arrays Color and alpha modulation is done per vertex (SDL_SetTextureColorMod and SDL_SetTextureAlphaMod are ignored).

Parameters

• renderer: the rendering context.
• texture: (optional) The SDL texture to use.
• xy: vertex positions.
• xy_stride: byte size to move from one element to the next element.
• color: vertex colors (as SDL_FColor).
• color_stride: byte size to move from one element to the next element.
• uv: vertex normalized texture coordinates.
• uv_stride: byte size to move from one element to the next element.
• num_vertices: number of vertices.
• indices: (optional) An array of indices into the ‘vertices’ arrays, if NULL all vertices will be rendered in sequential order.
• num_indices: number of indices.
• size_indices: index size: 1 (byte), 2 (short), 4 (int).

Return value

Returns true on success or false on failure; call SDL_GetError() for more information.

Thread safety

This function should only be called on the main thread.

Availability

This function is available since SDL 3.2.0.
